I have a 6.5 Tikka T3X lite that I had chopped to 16.5”. I’m running a TBAC Ultra 7 on the end. Prior to chopping the barrel I was shooting hornaday 143g eldx. I’m planning on taking the rifle out in the next week or two to get sighted back in and shoot different factory loads. This is going to be this years primary hunting rifle for whitetail with shots being under 200 yards. My question is, should I shoot something in the 130ish grain, to pick up some velocity or does it really matter? If I should step down in grain, what factory ammo would you choose?
